Institute of Applied Microelectronics and Computer Engineering College of Computer Science and Electrical Engineering, University of Rostock Spezielle Anwendungen des VLSI-Entwurfs Special applications of VLSI design Commands Used -Desired Speed, Frequency set_max_frequency -Desired Area set_max_area -Desired Power set_max_dyn_power -Max Capacitance of between 0,04 and 0,03 used but eventually 0,04. -Fan out of between 2 and 4,but 2 and 3 resulted in various Violations.

Institute of Applied Microelectronics and Computer Engineering College of Computer Science and Electrical Engineering, University of Rostock Spezielle Anwendungen des VLSI-Entwurfs Special applications of VLSI design -Violations during Optimization: # area, * fanout, ~ Slack -Caused by trial and error methods when setting constrainsts -It is expected : Low fanout,low power consumption but higher speed -Fan out increase – increase in Load capacitance hence increased dyn power consumption !Synopsys could resort to larger gates which may increase power consumption due to large input capacitances -Smaller area-smaller critical path which should reduce power Results/Analysis

Institute of Applied Microelectronics and Computer Engineering College of Computer Science and Electrical Engineering, University of Rostock Spezielle Anwendungen des VLSI-Entwurfs Special applications of VLSI design Conclusion The Results do not entirely correspond to the expected Pattern due to the prescence of Violations in Timing,Area,Capacitance and Fan out Constraints
